White Flex Circuitry

White Flex Circuit Technology by Spectra Symbol

…to decrease TCO (Total Cost of Ownership) by up to 50% from standard circuitry, assembly, and wiring.

Flexibly Circuitry = Increased Value

Description

Features

  • Replacement for a Circuit Board and Wires (quality assembly, lower costs).
  • Reduce weight and space (form factor as low as 0.005″).
  • Flex! It can bend where needed in design.
  • White Flex cut costs in half from traditional Kapton Flex
  • ROHS Compliant Assemblies
